Skunk turned yellow, other sprouts ok. Wtf?

Checkout the pic. This guy was growing really fast, a lot faster than the others and all of the sudden turned yellow.

His leaves went down, used to be up.

He doesn't look too happy.

The only thing I did was release the roots from a confinment that it filled

Now the roots have the room to grow down into the DWC reservoir

What can it be? Other sprouts in the same system look blue-greenish

Using universal nutes at 1/5 strength

The lights are CFL tubes 18w really close to them

Flash update - this guy "got up" this morning.

The upper leaves are now reaching towards the light, while the lower leaves are still down

All I did yesterday was add a tiny bit more nutes (I use a "universal" mix of liquid nutes)

Must have been some kind of defficiency

it has to be the light one of mine is doing the same but i have no nuts in my dwc

Huh, interesting

Too much light?

Not enough light?

Too close?

Too far?

i think its to close i have 400 mh its hard man to get it right its my first time

I've got 2 fluro tubes, so I can't imagine it being too close

There are good 1.5-2" between the sprouts and the lights

But that guy just got huge stimulus for root growth (no obstacles, they now can grow right down into the DWC res
